Hello,

I have some trouble building on XCode 9 for ios11 a project from the sample HelloARSlam from Unity 2017.2

I have a linker error for a Lapack lib:

Undefined symbols for architecture arm64:

  "_sgels_", referenced from:

      l4384 in libEasyARUnity.a(libEasyARUnity.a-arm64-master.o)

  "_sgesv_", referenced from:

      l4382 in libEasyARUnity.a(libEasyARUnity.a-arm64-master.o)

  "_sgeev_", referenced from:

      l4376 in libEasyARUnity.a(libEasyARUnity.a-arm64-master.o)

  "_sgesvd_", referenced from:

      l4363 in libEasyARUnity.a(libEasyARUnity.a-arm64-master.o)

      l4365 in libEasyARUnity.a(libEasyARUnity.a-arm64-master.o)

      l4372 in libEasyARUnity.a(libEasyARUnity.a-arm64-master.o)

      l4378 in libEasyARUnity.a(libEasyARUnity.a-arm64-master.o)

      l4380 in libEasyARUnity.a(libEasyARUnity.a-arm64-master.o)

      l4399 in libEasyARUnity.a(libEasyARUnity.a-arm64-master.o)

      l4409 in libEasyARUnity.a(libEasyARUnity.a-arm64-master.o)

      ...

  "_ssyev_", referenced from:

      l4354 in libEasyARUnity.a(libEasyARUnity.a-arm64-master.o)

      l4357 in libEasyARUnity.a(libEasyARUnity.a-arm64-master.o)

      l4360 in libEasyARUnity.a(libEasyARUnity.a-arm64-master.o)

ld: symbol(s) not found for architecture arm64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any hints?

I think I did what is in the documentation with libc++ and BITCODE.

Thank you,

Ben
